312-49V11 Question #118: Real Exam Question with Answer & Explanation
The correct answer is B. 4 sectors; it may cause inefficiency in space utilization on the disk. Although 1.5KB equals 1536 bytes (which is 3 sectors at 512 bytes/sector), file systems often allocate storage in clusters/blocks larger than a single sector (e.g., 2KB or 4KB blocks). If the allocation unit is 2KB, the file may occupy 4 sectors (2048 bytes), creating slack space
Question
Options
- A2 sectors; the file might be fragmented, making it harder to retrieve
- B4 sectors; it may cause inefficiency in space utilization on the disk
- C3 sectors; it may increase the retrieval time due to increased sector overhead
- D3 sectors; the file might be fragmented, making it harder to retrieve
Explanation
Although 1.5KB equals 1536 bytes (which is 3 sectors at 512 bytes/sector), file systems often allocate storage in clusters/blocks larger than a single sector (e.g., 2KB or 4KB blocks). If the allocation unit is 2KB, the file may occupy 4 sectors (2048 bytes), creating slack space and inefficient utilization. That slack space can also contain remnants of prior data-relevant for
